Specification of Letters Patent.

Patented Dec. 14, 1915.

Application led March 18, 1910. Serial No. 550,218.

T0 all `whom t may concern:

Be it known that I, PAUL BROWN KLUGH, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Pedal-Doors or the like, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying dra-wings, forming a part of this specification.

My invention relates to mechanism for closures for recesses, such as pedal doors and the like, and in its preferred form, is adapted for use in combination with a closure for a recess within which an extensible member is mounted, which closure is to be opened to permit the extension of said member from within said recess to the exterior, whereupon the closure is again allowed to assume its normal position of closing the recess, means being provided whereby the extensible member may remain in its extended position even though the closure is in its normal closed position. In the preferred form of my invention, this closure is made in two hinged parts, and is under the control of an arm actuated by a lever, which lever, when operated, moves the closure to open the recess, and which closure may then again be closed into its normal position.

I will describe my invention more in detail by reference to the accompanying.,r drawings, illustrating one embodiment thereof, in which- Figure 1 is a side view, partly in section, of my improved mechanism; Fig. 2 is a detail view of the lever mechanism; and Fig. 3 is a rear view of the closure in its normal or closed position, with the lever mechanism removed.

Referring more particularly to Fig. 1, in which I have shown the invention as applied to a piano player, or player piano,` I show the lower portion of a player piano, 1, within the base of which bellows 2 is mounted, which bellows is adapted for actuation by means of pedals 3, which pedals and bellows, are more' clearly set forth in my Patent No. 874,408, issued December 24, 1907. The pedals are adapted for extension into the dotted position shown in Fig. 1, when in use, at which time the arms 4 and 5 extend through slots such as 6, 6, to permit the pedals to operate the bellows. When the pedals are not in use, they are placed a position indicated by full lines in Fig. 1, directly against the bellows mechanism. A removable panel 25 is placed vertically within the base of the piano in front of bellows Q. The panel 25 is held at its top when in normal position as shown in Fig. 1, by one or more spring catches or latches 26. The panel 25 is also slotted at its top as shown at 27. Panel 25 forms a recess for the bellows and pedals and has an aperture through which the pedals may be folded and unfolded. The recess within which these pedals are mounted is adapted to be closed by a closure 7, hinged at 8, and formed of two hinged parts, 9 and 10, hinged together at 11, the closure 7 being supported by the portion of the panel 25 immediately above the part 9 and said closure 7 closing said aperture in said panel Stops 12, 12 limit the movement of the closure. The closure is also provided with a catch 13, and a spring 14, which, by virtue of the spring action, holds the closure in its normal position, when it is once brought in that position. In order to withdraw the pedals, the closure must be opened, and while the pedals remain withdrawn, the closure may again be closed, thus to present a good appearance, and can remain so until the pedals are again to be placed within the recess, as will be apparent. y

In order to properly open the closure, I provide an L-shaped lever 15, pivoted at 16, in a bracket 17, and associate with this lever 15 a connecting link 18, which is hinged to a lever 19. The lever 19 is pivoted at 20, and has a handle 21, the free end of the lever moving within a guide 22. Now, when the right hand extremity of the lever 19, as shown in Fig. 9., is drawn toward the operator, the lever 15 occupies the dotted position shown in Fig. 1, and opens the closure, whereupon the pedals may be withdrawn. Then, the closure is again placed in its normal position, the slots 6 accommodating the extensible members or pedals, and the spring 14 holds the closure in place. lVhen it is desired to again replace the pedals, the lever 19 is again actuated to open the closure, after which the pedals are replaced, and the closure moves to occupy its normal position, as shown in full lines in Fig. 1.

While I have herein shown and particularly described the preferred embodiment of my invention, I do not desire to llmit my- ISOr self to the precise construction and arrangement as herein set forth, but

Having thus described my invention, what I claim as new and desire to secure by Let; ters Patent 1s:
